YARN AND METHOD OF MAKING SAME.

Specification of Letters Patent.

Patented June 14, 1910.

Application filed September 20, 1909. Serial No. 518,471.

To all whom it may concern:

Be it known that 1, JAMES Gr. HARRISON, a citizen of the United States,residing at Lawrence, county of Essex, and State of Massachusetts, haveinvented certain new and useful Improvements in Yarns and the Method ofMaking Same, of which the following is a specification.

Myinvention relates to yarn and the method of making the same and alsoto fabric woven from said yarn; and particularly to a yarn especiallyadapted for use as a warp thread in weaving and consisting of a strandof paper and a strand of wool, cotton, linen or similar materialsuitably twisted together.

The object of my invention is to provide 'a thread as mentioned in whichthe component parts shall be so secured to each other as to preventslipping of one upon the other.

A further and particular object of my invention is to provide a threadcharacterized as above mentioned which shall break even.

Other objects will appear hereinafter.

In carrying out my invention I provide a twisted paper strand and aboutthis twist a strand of the other material to be used.

he last mentioned strand is wrapped about tie paper strand in thereversed direction from the twist of the paper strand, and as the twothreads are twisted together the paper is partially untwisted causingthe same to spread or increase in diameter be tween the convolutions ofthe other thread,

thereby causing the latter to be embedded in the aper without puttingundue strain upon either thread to weaken the same. This prevents theslipping of the component parts and also leads the two threads at auniform tension so that when in the loom one will not break without theother.

My invention will be more readily understood by reference to theaccompanying drawings forming a part of this specifica- ;tion and inwhich:

Figure 1 is a view of the paper thread before being subjected to theprocess above mentioned.- Fig. 2 is a similar view of both threads readyto be twisted together. Fig.-

3 is a similar view of the finished product, and Fig. 4 is a view of apiece of fabric woven rom the yarn.

Referring now to the drawings, 1 indicates a twisted paper thread suchas I employ .in carrying out my invention, and 2 indicates a thread ofwool, cotton, linen or other suitable materials. The paper thread isfirst twisted to a greater degree than it is desired for it to be in thefinished product. The two threads are then twisted together in thereversed direction from the twist of the paper thread and as they aretwisted together the aper thread is partially or entirely untwisted asdesired. This causes the paper to expand or increase in diameter, as at3, between the convolutions a of the other thread, thereby embedding thelatter therein. It is obvious that by ex panding the paper within theother thread it is not necessary to place greater tension on the latterto embed the same therein.

In Fig. 4 I have illustrated a piece of fabric woven with a threadcomposed of the yarn above described, said yarn running in one directionwhile the threads running in the opposite direction may be of anysuitable material such as linen, cotton or the like, 5 indicating thelatter threads. By dyeing the paper and the wool of different colors anartistic effect is produced and by running several threads of which thepaper is dyed of different colors various patterns may be formed in themanner well known in the art' and by having the wool of each thread ofthe same color asoft effect and harmony through the entire fabric isproduced. c

' Having described my invention what I claim as new and desire toreceive protection upon is:
